If you’re planning to leave your car unused for weeks or even months, it’s important to store it properly. Long-term car storage without the right preparation can lead to flat batteries, tyre damage, rust, and costly mechanical problems.
Whether you’re travelling, working abroad, or simply not using your vehicle regularly, these simple tips will help keep your car in excellent condition while it’s off the road.
1. Store Your Car Somewhere Safe and Dry
Where you keep your car matters. A garage is ideal because it protects your vehicle from rain, frost, bird droppings, and general weather damage. If you don’t have access to a garage, invest in a high-quality breathable car cover to protect the paintwork and bodywork.
Avoid parking under trees if possible, as sap and bird mess can damage your paint over time.

2. Wash and Wax the Car Before Storage
It might seem unnecessary to clean a car you’re not using, but dirt, bird droppings, and road salt can damage paintwork if left sitting for long periods.
Before storing your car:
- Wash the exterior thoroughly
- Clean the wheels and arches
- Vacuum the interior
- Remove rubbish and food
- Apply a coat of wax for extra paint protection
A clean car is far less likely to develop cosmetic damage while in storage.
3. Fill the Fuel Tank
Leaving a fuel tank nearly empty during storage can cause condensation to build up inside the tank. Over time, this moisture can lead to corrosion and fuel contamination.
If you’re storing your car for more than a month:
- Fill the tank before storage
- Add a fuel stabiliser if possible
Fuel stabiliser helps prevent petrol or diesel from deteriorating and can keep fuel usable for several months.
4. Change the Oil
Old engine oil contains contaminants that can damage engine components over time. Changing the oil and filter before storing your vehicle helps keep the engine protected while it sits unused.
It’s a simple maintenance job that could save you money later.

5. Avoid Using the Handbrake
Leaving the handbrake engaged for long periods can cause the brake pads to stick to the discs, especially in damp or cold conditions.
Instead:
- Leave the car in gear (or Park for automatics)
- Use wheel chocks or tyre stoppers to prevent movement
This reduces the risk of seized brakes when you return to the vehicle.
6. Protect the Battery
A car battery slowly drains even when the vehicle isn’t being used. If left too long, the battery may go flat completely.
To avoid this:
- Disconnect the battery
- Or use a trickle charger/battery maintainer
Starting the car occasionally can also help, but ideally the vehicle should be driven properly rather than just idled.
7. Check Your Tyres
Cars left stationary for long periods can develop flat spots on their tyres.
To help prevent this:
- Inflate tyres slightly above the recommended pressure
- Move the car occasionally if possible
This helps maintain tyre shape and condition.
Final Thoughts
Proper long-term car storage is all about prevention. A few simple steps can help you avoid expensive repairs and ensure your car is ready to drive when you need it again.
However, if you no longer need the vehicle, storing it may not be worth the ongoing costs.
